Check Digit Verification of cas no
The CAS Registry Mumber 203790-61-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,3,7,9 and 0 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 203790-61:
(8*2)+(7*0)+(6*3)+(5*7)+(4*9)+(3*0)+(2*6)+(1*1)=118
118 % 10 = 8
So 203790-61-8 is a valid CAS Registry Number.
