15431-97-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 15431-97-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,4,3 and 1 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 15431-97:
(7*1)+(6*5)+(5*4)+(4*3)+(3*1)+(2*9)+(1*7)=97
97 % 10 = 7
So 15431-97-7 is a valid CAS Registry Number.
