Check Digit Verification of cas no
The CAS Registry Mumber 155178-83-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,1,7 and 8 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 155178-83:
(8*1)+(7*5)+(6*5)+(5*1)+(4*7)+(3*8)+(2*8)+(1*3)=149
149 % 10 = 9
So 155178-83-9 is a valid CAS Registry Number.
