Check Digit Verification of cas no
The CAS Registry Mumber 161199-03-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,1,1,9 and 9 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 161199-03:
(8*1)+(7*6)+(6*1)+(5*1)+(4*9)+(3*9)+(2*0)+(1*3)=127
127 % 10 = 7
So 161199-03-7 is a valid CAS Registry Number.
