332908-81-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 332908-81-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,2,9,0 and 8 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 332908-81:
(8*3)+(7*3)+(6*2)+(5*9)+(4*0)+(3*8)+(2*8)+(1*1)=143
143 % 10 = 3
So 332908-81-3 is a valid CAS Registry Number.
