Check Digit Verification of cas no
The CAS Registry Mumber 1137-99-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,3 and 7 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1137-99:
(6*1)+(5*1)+(4*3)+(3*7)+(2*9)+(1*9)=71
71 % 10 = 1
So 1137-99-1 is a valid CAS Registry Number.
