4Check Digit Verification of cas no
The CAS Registry Mumber 6661-42-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,6,6 and 1 respectively; the second part has 2 digits, 4 and 2 respectively.Calculate Digit Verification of CAS Registry Number 6661-42:
(6*6)+(5*6)+(4*6)+(3*1)+(2*4)+(1*2)=103
103 % 10 = 3
So 6661-42-3 is a valid CAS Registry Number.
