Check Digit Verification of cas no
The CAS Registry Mumber 15649-41-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,6,4 and 9 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 15649-41:
(7*1)+(6*5)+(5*6)+(4*4)+(3*9)+(2*4)+(1*1)=119
119 % 10 = 9
So 15649-41-9 is a valid CAS Registry Number.
