77871-34-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77871-34-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,8,7 and 1 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 77871-34:
(7*7)+(6*7)+(5*8)+(4*7)+(3*1)+(2*3)+(1*4)=172
172 % 10 = 2
So 77871-34-2 is a valid CAS Registry Number.
