1Check Digit Verification of cas no
The CAS Registry Mumber 3841-15-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,8,4 and 1 respectively; the second part has 2 digits, 1 and 5 respectively.Calculate Digit Verification of CAS Registry Number 3841-15:
(6*3)+(5*8)+(4*4)+(3*1)+(2*1)+(1*5)=84
84 % 10 = 4
So 3841-15-4 is a valid CAS Registry Number.
