Check Digit Verification of cas no
The CAS Registry Mumber 5850-39-5 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, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 5850-39:
(6*5)+(5*8)+(4*5)+(3*0)+(2*3)+(1*9)=105
105 % 10 = 5
So 5850-39-5 is a valid CAS Registry Number.
