93921-42-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 93921-42-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,9,2 and 1 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 93921-42:
(7*9)+(6*3)+(5*9)+(4*2)+(3*1)+(2*4)+(1*2)=147
147 % 10 = 7
So 93921-42-7 is a valid CAS Registry Number.
