Check Digit Verification of cas no
The CAS Registry Mumber 15071-66-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,0,7 and 1 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 15071-66:
(7*1)+(6*5)+(5*0)+(4*7)+(3*1)+(2*6)+(1*6)=86
86 % 10 = 6
So 15071-66-6 is a valid CAS Registry Number.
