Check Digit Verification of cas no
The CAS Registry Mumber 61551-69-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,5,5 and 1 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 61551-69:
(7*6)+(6*1)+(5*5)+(4*5)+(3*1)+(2*6)+(1*9)=117
117 % 10 = 7
So 61551-69-7 is a valid CAS Registry Number.
