236427-76-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 236427-76-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,3,6,4,2 and 7 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 236427-76:
(8*2)+(7*3)+(6*6)+(5*4)+(4*2)+(3*7)+(2*7)+(1*6)=142
142 % 10 = 2
So 236427-76-2 is a valid CAS Registry Number.
