136877-40-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 136877-40-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,8,7 and 7 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 136877-40:
(8*1)+(7*3)+(6*6)+(5*8)+(4*7)+(3*7)+(2*4)+(1*0)=162
162 % 10 = 2
So 136877-40-2 is a valid CAS Registry Number.
