229974-97-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 229974-97-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,9,9,7 and 4 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 229974-97:
(8*2)+(7*2)+(6*9)+(5*9)+(4*7)+(3*4)+(2*9)+(1*7)=194
194 % 10 = 4
So 229974-97-4 is a valid CAS Registry Number.
