Check Digit Verification of cas no
The CAS Registry Mumber 138234-61-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,2,3 and 4 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 138234-61:
(8*1)+(7*3)+(6*8)+(5*2)+(4*3)+(3*4)+(2*6)+(1*1)=124
124 % 10 = 4
So 138234-61-4 is a valid CAS Registry Number.
