4947-08-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4947-08-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,4 and 7 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 4947-08:
(6*4)+(5*9)+(4*4)+(3*7)+(2*0)+(1*8)=114
114 % 10 = 4
So 4947-08-4 is a valid CAS Registry Number.
