Check Digit Verification of cas no
The CAS Registry Mumber 4229-15-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,2 and 9 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 4229-15:
(6*4)+(5*2)+(4*2)+(3*9)+(2*1)+(1*5)=76
76 % 10 = 6
So 4229-15-6 is a valid CAS Registry Number.
