Check Digit Verification of cas no
The CAS Registry Mumber 332015-61-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,2,0,1 and 5 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 332015-61:
(8*3)+(7*3)+(6*2)+(5*0)+(4*1)+(3*5)+(2*6)+(1*1)=89
89 % 10 = 9
So 332015-61-9 is a valid CAS Registry Number.
