3947-38-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3947-38-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,4 and 7 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 3947-38:
(6*3)+(5*9)+(4*4)+(3*7)+(2*3)+(1*8)=114
114 % 10 = 4
So 3947-38-4 is a valid CAS Registry Number.
