123992-71-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 123992-71-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,9,9 and 2 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 123992-71:
(8*1)+(7*2)+(6*3)+(5*9)+(4*9)+(3*2)+(2*7)+(1*1)=142
142 % 10 = 2
So 123992-71-2 is a valid CAS Registry Number.
