Check Digit Verification of cas no
The CAS Registry Mumber 5850-41-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,8,5 and 0 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 5850-41:
(6*5)+(5*8)+(4*5)+(3*0)+(2*4)+(1*1)=99
99 % 10 = 9
So 5850-41-9 is a valid CAS Registry Number.
