Check Digit Verification of cas no
The CAS Registry Mumber 494804-64-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,4,8,0 and 4 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 494804-64:
(8*4)+(7*9)+(6*4)+(5*8)+(4*0)+(3*4)+(2*6)+(1*4)=187
187 % 10 = 7
So 494804-64-7 is a valid CAS Registry Number.
