21313-98-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 21313-98-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,3,1 and 3 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 21313-98:
(7*2)+(6*1)+(5*3)+(4*1)+(3*3)+(2*9)+(1*8)=74
74 % 10 = 4
So 21313-98-4 is a valid CAS Registry Number.
