Check Digit Verification of cas no
The CAS Registry Mumber 117048-56-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,0,4 and 8 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 117048-56:
(8*1)+(7*1)+(6*7)+(5*0)+(4*4)+(3*8)+(2*5)+(1*6)=113
113 % 10 = 3
So 117048-56-3 is a valid CAS Registry Number.

, p. 60 - 63 (2007/10/03)
An effective deprotective method of spiro 3-cyclic thiaza ketal of steroidal 1,4-dien-3-ones using alkyl vinyl ether in the presence of protic acid followed by the treatment of aqueous alkali was described. This novel protocol could be fulfilled under mild condition with high yield. The mechanism mediated by a carbonium ion formed in situ was clarified by the capture of the cleaved fragment.
