Check Digit Verification of cas no
The CAS Registry Mumber 1338549-02-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,8,5,4 and 9 respectively; the second part has 2 digits, 0 and 2 respectively.Calculate Digit Verification of CAS Registry Number 1338549-02:
(9*1)+(8*3)+(7*3)+(6*8)+(5*5)+(4*4)+(3*9)+(2*0)+(1*2)=172
172 % 10 = 2
So 1338549-02-2 is a valid CAS Registry Number.
