171232-79-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 171232-79-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,1,2,3 and 2 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 171232-79:
(8*1)+(7*7)+(6*1)+(5*2)+(4*3)+(3*2)+(2*7)+(1*9)=114
114 % 10 = 4
So 171232-79-4 is a valid CAS Registry Number.
