Check Digit Verification of cas no
The CAS Registry Mumber 93050-79-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,0,5 and 0 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 93050-79:
(7*9)+(6*3)+(5*0)+(4*5)+(3*0)+(2*7)+(1*9)=124
124 % 10 = 4
So 93050-79-4 is a valid CAS Registry Number.
