1197241-69-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1197241-69-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,7,2,4 and 1 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1197241-69:
(9*1)+(8*1)+(7*9)+(6*7)+(5*2)+(4*4)+(3*1)+(2*6)+(1*9)=172
172 % 10 = 2
So 1197241-69-2 is a valid CAS Registry Number.
