Check Digit Verification of cas no
The CAS Registry Mumber 70474-34-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,4,7 and 4 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 70474-34:
(7*7)+(6*0)+(5*4)+(4*7)+(3*4)+(2*3)+(1*4)=119
119 % 10 = 9
So 70474-34-9 is a valid CAS Registry Number.
