Hazard
Moderately toxic by ingestion.
Check Digit Verification of cas no
The CAS Registry Mumber 64037-20-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,0,3 and 7 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 64037-20:
(7*6)+(6*4)+(5*0)+(4*3)+(3*7)+(2*2)+(1*0)=103
103 % 10 = 3
So 64037-20-3 is a valid CAS Registry Number.
