Check Digit Verification of cas no
The CAS Registry Mumber 1204232-04-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,4,2,3 and 2 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1204232-04:
(9*1)+(8*2)+(7*0)+(6*4)+(5*2)+(4*3)+(3*2)+(2*0)+(1*4)=81
81 % 10 = 1
So 1204232-04-1 is a valid CAS Registry Number.
