Check Digit Verification of cas no
The CAS Registry Mumber 104921-13-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,9,2 and 1 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 104921-13:
(8*1)+(7*0)+(6*4)+(5*9)+(4*2)+(3*1)+(2*1)+(1*3)=93
93 % 10 = 3
So 104921-13-3 is a valid CAS Registry Number.
