1515871-94-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1515871-94-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,1,5,8,7 and 1 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1515871-94:
(9*1)+(8*5)+(7*1)+(6*5)+(5*8)+(4*7)+(3*1)+(2*9)+(1*4)=179
179 % 10 = 9
So 1515871-94-9 is a valid CAS Registry Number.
