Check Digit Verification of cas no
The CAS Registry Mumber 945491-90-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,5,4,9 and 1 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 945491-90:
(8*9)+(7*4)+(6*5)+(5*4)+(4*9)+(3*1)+(2*9)+(1*0)=207
207 % 10 = 7
So 945491-90-7 is a valid CAS Registry Number.
