99967-47-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99967-47-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,9,6 and 7 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 99967-47:
(7*9)+(6*9)+(5*9)+(4*6)+(3*7)+(2*4)+(1*7)=222
222 % 10 = 2
So 99967-47-2 is a valid CAS Registry Number.
