72923-17-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 72923-17-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,9,2 and 3 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 72923-17:
(7*7)+(6*2)+(5*9)+(4*2)+(3*3)+(2*1)+(1*7)=132
132 % 10 = 2
So 72923-17-2 is a valid CAS Registry Number.
