Check Digit Verification of cas no
The CAS Registry Mumber 136864-77-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,8,6 and 4 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 136864-77:
(8*1)+(7*3)+(6*6)+(5*8)+(4*6)+(3*4)+(2*7)+(1*7)=162
162 % 10 = 2
So 136864-77-2 is a valid CAS Registry Number.
