90834-21-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 90834-21-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,8,3 and 4 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 90834-21:
(7*9)+(6*0)+(5*8)+(4*3)+(3*4)+(2*2)+(1*1)=132
132 % 10 = 2
So 90834-21-2 is a valid CAS Registry Number.
