31736-40-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 31736-40-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,7,3 and 6 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 31736-40:
(7*3)+(6*1)+(5*7)+(4*3)+(3*6)+(2*4)+(1*0)=100
100 % 10 = 0
So 31736-40-0 is a valid CAS Registry Number.
