Check Digit Verification of cas no
The CAS Registry Mumber 913081-21-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,3,0,8 and 1 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 913081-21:
(8*9)+(7*1)+(6*3)+(5*0)+(4*8)+(3*1)+(2*2)+(1*1)=137
137 % 10 = 7
So 913081-21-7 is a valid CAS Registry Number.
