Check Digit Verification of cas no
The CAS Registry Mumber 137157-07-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,1,5 and 7 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 137157-07:
(8*1)+(7*3)+(6*7)+(5*1)+(4*5)+(3*7)+(2*0)+(1*7)=124
124 % 10 = 4
So 137157-07-4 is a valid CAS Registry Number.
