633294-12-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 633294-12-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,3,2,9 and 4 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 633294-12:
(8*6)+(7*3)+(6*3)+(5*2)+(4*9)+(3*4)+(2*1)+(1*2)=149
149 % 10 = 9
So 633294-12-9 is a valid CAS Registry Number.
