947381-32-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 947381-32-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,7,3,8 and 1 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 947381-32:
(8*9)+(7*4)+(6*7)+(5*3)+(4*8)+(3*1)+(2*3)+(1*2)=200
200 % 10 = 0
So 947381-32-0 is a valid CAS Registry Number.
