27157-73-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 27157-73-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,1,5 and 7 respectively; the second part has 2 digits, 7 and 3 respectively.Calculate Digit Verification of CAS Registry Number 27157-73:
(7*2)+(6*7)+(5*1)+(4*5)+(3*7)+(2*7)+(1*3)=119
119 % 10 = 9
So 27157-73-9 is a valid CAS Registry Number.
