Check Digit Verification of cas no
The CAS Registry Mumber 137071-17-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,0,7 and 1 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 137071-17:
(8*1)+(7*3)+(6*7)+(5*0)+(4*7)+(3*1)+(2*1)+(1*7)=111
111 % 10 = 1
So 137071-17-1 is a valid CAS Registry Number.
