Check Digit Verification of cas no
The CAS Registry Mumber 940950-77-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,0,9,5 and 0 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 940950-77:
(8*9)+(7*4)+(6*0)+(5*9)+(4*5)+(3*0)+(2*7)+(1*7)=186
186 % 10 = 6
So 940950-77-6 is a valid CAS Registry Number.
