93221-34-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 93221-34-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,2,2 and 1 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 93221-34:
(7*9)+(6*3)+(5*2)+(4*2)+(3*1)+(2*3)+(1*4)=112
112 % 10 = 2
So 93221-34-2 is a valid CAS Registry Number.
