Check Digit Verification of cas no
The CAS Registry Mumber 1551-39-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,5 and 1 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1551-39:
(6*1)+(5*5)+(4*5)+(3*1)+(2*3)+(1*9)=69
69 % 10 = 9
So 1551-39-9 is a valid CAS Registry Number.
