1187371-77-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1187371-77-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,7,3,7 and 1 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1187371-77:
(9*1)+(8*1)+(7*8)+(6*7)+(5*3)+(4*7)+(3*1)+(2*7)+(1*7)=182
182 % 10 = 2
So 1187371-77-2 is a valid CAS Registry Number.
