Check Digit Verification of cas no
The CAS Registry Mumber 31886-41-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,8,8 and 6 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 31886-41:
(7*3)+(6*1)+(5*8)+(4*8)+(3*6)+(2*4)+(1*1)=126
126 % 10 = 6
So 31886-41-6 is a valid CAS Registry Number.
