Check Digit Verification of cas no
The CAS Registry Mumber 10042-91-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,0,4 and 2 respectively; the second part has 2 digits, 9 and 1 respectively.Calculate Digit Verification of CAS Registry Number 10042-91:
(7*1)+(6*0)+(5*0)+(4*4)+(3*2)+(2*9)+(1*1)=48
48 % 10 = 8
So 10042-91-8 is a valid CAS Registry Number.
