Check Digit Verification of cas no
The CAS Registry Mumber 61854-36-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,8,5 and 4 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 61854-36:
(7*6)+(6*1)+(5*8)+(4*5)+(3*4)+(2*3)+(1*6)=132
132 % 10 = 2
So 61854-36-2 is a valid CAS Registry Number.
