Check Digit Verification of cas no
The CAS Registry Mumber 136603-73-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,6,0 and 3 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 136603-73:
(8*1)+(7*3)+(6*6)+(5*6)+(4*0)+(3*3)+(2*7)+(1*3)=121
121 % 10 = 1
So 136603-73-1 is a valid CAS Registry Number.
