Check Digit Verification of cas no
The CAS Registry Mumber 1613668-02-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,1,3,6,6 and 8 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1613668-02:
(9*1)+(8*6)+(7*1)+(6*3)+(5*6)+(4*6)+(3*8)+(2*0)+(1*2)=162
162 % 10 = 2
So 1613668-02-2 is a valid CAS Registry Number.
