Check Digit Verification of cas no
The CAS Registry Mumber 135103-71-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,1,0 and 3 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 135103-71:
(8*1)+(7*3)+(6*5)+(5*1)+(4*0)+(3*3)+(2*7)+(1*1)=88
88 % 10 = 8
So 135103-71-8 is a valid CAS Registry Number.
