Check Digit Verification of cas no
The CAS Registry Mumber 74158-38-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,1,5 and 8 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 74158-38:
(7*7)+(6*4)+(5*1)+(4*5)+(3*8)+(2*3)+(1*8)=136
136 % 10 = 6
So 74158-38-6 is a valid CAS Registry Number.
