942040-77-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 942040-77-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,2,0,4 and 0 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 942040-77:
(8*9)+(7*4)+(6*2)+(5*0)+(4*4)+(3*0)+(2*7)+(1*7)=149
149 % 10 = 9
So 942040-77-9 is a valid CAS Registry Number.
