80337-42-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80337-42-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,3,3 and 7 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 80337-42:
(7*8)+(6*0)+(5*3)+(4*3)+(3*7)+(2*4)+(1*2)=114
114 % 10 = 4
So 80337-42-4 is a valid CAS Registry Number.
