293768-71-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 293768-71-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,3,7,6 and 8 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 293768-71:
(8*2)+(7*9)+(6*3)+(5*7)+(4*6)+(3*8)+(2*7)+(1*1)=195
195 % 10 = 5
So 293768-71-5 is a valid CAS Registry Number.
