Check Digit Verification of cas no
The CAS Registry Mumber 954154-12-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,5,4,1,5 and 4 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 954154-12:
(8*9)+(7*5)+(6*4)+(5*1)+(4*5)+(3*4)+(2*1)+(1*2)=172
172 % 10 = 2
So 954154-12-2 is a valid CAS Registry Number.
