93721-14-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 93721-14-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,7,2 and 1 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 93721-14:
(7*9)+(6*3)+(5*7)+(4*2)+(3*1)+(2*1)+(1*4)=133
133 % 10 = 3
So 93721-14-3 is a valid CAS Registry Number.
