1155911-74-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1155911-74-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,5,5,9,1 and 1 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1155911-74:
(9*1)+(8*1)+(7*5)+(6*5)+(5*9)+(4*1)+(3*1)+(2*7)+(1*4)=152
152 % 10 = 2
So 1155911-74-2 is a valid CAS Registry Number.
