236737-87-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 236737-87-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,3,6,7,3 and 7 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 236737-87:
(8*2)+(7*3)+(6*6)+(5*7)+(4*3)+(3*7)+(2*8)+(1*7)=164
164 % 10 = 4
So 236737-87-4 is a valid CAS Registry Number.
