Check Digit Verification of cas no
The CAS Registry Mumber 21966-50-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,9,6 and 6 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 21966-50:
(7*2)+(6*1)+(5*9)+(4*6)+(3*6)+(2*5)+(1*0)=117
117 % 10 = 7
So 21966-50-7 is a valid CAS Registry Number.
