Check Digit Verification of cas no
The CAS Registry Mumber 945905-49-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,5,9,0 and 5 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 945905-49:
(8*9)+(7*4)+(6*5)+(5*9)+(4*0)+(3*5)+(2*4)+(1*9)=207
207 % 10 = 7
So 945905-49-7 is a valid CAS Registry Number.
