Check Digit Verification of cas no
The CAS Registry Mumber 937203-99-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,3,7,2,0 and 3 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 937203-99:
(8*9)+(7*3)+(6*7)+(5*2)+(4*0)+(3*3)+(2*9)+(1*9)=181
181 % 10 = 1
So 937203-99-1 is a valid CAS Registry Number.
