919769-22-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 919769-22-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,9,7,6 and 9 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 919769-22:
(8*9)+(7*1)+(6*9)+(5*7)+(4*6)+(3*9)+(2*2)+(1*2)=225
225 % 10 = 5
So 919769-22-5 is a valid CAS Registry Number.
