Check Digit Verification of cas no
The CAS Registry Mumber 774216-20-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,7,4,2,1 and 6 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 774216-20:
(8*7)+(7*7)+(6*4)+(5*2)+(4*1)+(3*6)+(2*2)+(1*0)=165
165 % 10 = 5
So 774216-20-5 is a valid CAS Registry Number.
