Check Digit Verification of cas no
The CAS Registry Mumber 774483-95-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,7,4,4,8 and 3 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 774483-95:
(8*7)+(7*7)+(6*4)+(5*4)+(4*8)+(3*3)+(2*9)+(1*5)=213
213 % 10 = 3
So 774483-95-3 is a valid CAS Registry Number.
