Check Digit Verification of cas no
The CAS Registry Mumber 35642-64-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,5,6,4 and 2 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 35642-64:
(7*3)+(6*5)+(5*6)+(4*4)+(3*2)+(2*6)+(1*4)=119
119 % 10 = 9
So 35642-64-9 is a valid CAS Registry Number.
