1315168-21-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1315168-21-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,5,1,6 and 8 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1315168-21:
(9*1)+(8*3)+(7*1)+(6*5)+(5*1)+(4*6)+(3*8)+(2*2)+(1*1)=128
128 % 10 = 8
So 1315168-21-8 is a valid CAS Registry Number.
