1169876-61-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1169876-61-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,6,9,8,7 and 6 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1169876-61:
(9*1)+(8*1)+(7*6)+(6*9)+(5*8)+(4*7)+(3*6)+(2*6)+(1*1)=212
212 % 10 = 2
So 1169876-61-2 is a valid CAS Registry Number.
