947381-14-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 947381-14-8 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, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 947381-14:
(8*9)+(7*4)+(6*7)+(5*3)+(4*8)+(3*1)+(2*1)+(1*4)=198
198 % 10 = 8
So 947381-14-8 is a valid CAS Registry Number.
