Check Digit Verification of cas no
The CAS Registry Mumber 355131-38-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,5,5,1,3 and 1 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 355131-38:
(8*3)+(7*5)+(6*5)+(5*1)+(4*3)+(3*1)+(2*3)+(1*8)=123
123 % 10 = 3
So 355131-38-3 is a valid CAS Registry Number.
