Check Digit Verification of cas no
The CAS Registry Mumber 3738-04-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,7,3 and 8 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 3738-04:
(6*3)+(5*7)+(4*3)+(3*8)+(2*0)+(1*4)=93
93 % 10 = 3
So 3738-04-3 is a valid CAS Registry Number.
