4Check Digit Verification of cas no
The CAS Registry Mumber 6358-79-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,3,5 and 8 respectively; the second part has 2 digits, 7 and 9 respectively.Calculate Digit Verification of CAS Registry Number 6358-79:
(6*6)+(5*3)+(4*5)+(3*8)+(2*7)+(1*9)=118
118 % 10 = 8
So 6358-79-8 is a valid CAS Registry Number.
