Check Digit Verification of cas no
The CAS Registry Mumber 125612-11-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,6,1 and 2 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 125612-11:
(8*1)+(7*2)+(6*5)+(5*6)+(4*1)+(3*2)+(2*1)+(1*1)=95
95 % 10 = 5
So 125612-11-5 is a valid CAS Registry Number.
