Check Digit Verification of cas no
The CAS Registry Mumber 93951-21-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,9,5 and 1 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 93951-21:
(7*9)+(6*3)+(5*9)+(4*5)+(3*1)+(2*2)+(1*1)=154
154 % 10 = 4
So 93951-21-4 is a valid CAS Registry Number.
