1221237-99-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1221237-99-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,1,2,3 and 7 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1221237-99:
(9*1)+(8*2)+(7*2)+(6*1)+(5*2)+(4*3)+(3*7)+(2*9)+(1*9)=115
115 % 10 = 5
So 1221237-99-5 is a valid CAS Registry Number.
