93831-74-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 93831-74-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,8,3 and 1 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 93831-74:
(7*9)+(6*3)+(5*8)+(4*3)+(3*1)+(2*7)+(1*4)=154
154 % 10 = 4
So 93831-74-4 is a valid CAS Registry Number.
