Check Digit Verification of cas no
The CAS Registry Mumber 374622-18-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,7,4,6,2 and 2 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 374622-18:
(8*3)+(7*7)+(6*4)+(5*6)+(4*2)+(3*2)+(2*1)+(1*8)=151
151 % 10 = 1
So 374622-18-1 is a valid CAS Registry Number.
