Check Digit Verification of cas no
The CAS Registry Mumber 27157-94-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,1,5 and 7 respectively; the second part has 2 digits, 9 and 4 respectively.Calculate Digit Verification of CAS Registry Number 27157-94:
(7*2)+(6*7)+(5*1)+(4*5)+(3*7)+(2*9)+(1*4)=124
124 % 10 = 4
So 27157-94-4 is a valid CAS Registry Number.
