31862-40-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 31862-40-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,8,6 and 2 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 31862-40:
(7*3)+(6*1)+(5*8)+(4*6)+(3*2)+(2*4)+(1*0)=105
105 % 10 = 5
So 31862-40-5 is a valid CAS Registry Number.
