Check Digit Verification of cas no
The CAS Registry Mumber 61558-12-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,5,5 and 8 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 61558-12:
(7*6)+(6*1)+(5*5)+(4*5)+(3*8)+(2*1)+(1*2)=121
121 % 10 = 1
So 61558-12-1 is a valid CAS Registry Number.
