Check Digit Verification of cas no
The CAS Registry Mumber 275377-34-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,7,5,3,7 and 7 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 275377-34:
(8*2)+(7*7)+(6*5)+(5*3)+(4*7)+(3*7)+(2*3)+(1*4)=169
169 % 10 = 9
So 275377-34-9 is a valid CAS Registry Number.
