93831-72-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 93831-72-2 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 2 respectively.
Calculate Digit Verification of CAS Registry Number 93831-72:
(7*9)+(6*3)+(5*8)+(4*3)+(3*1)+(2*7)+(1*2)=152
152 % 10 = 2
So 93831-72-2 is a valid CAS Registry Number.
