Check Digit Verification of cas no
The CAS Registry Mumber 152565-63-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,2,5,6 and 5 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 152565-63:
(8*1)+(7*5)+(6*2)+(5*5)+(4*6)+(3*5)+(2*6)+(1*3)=134
134 % 10 = 4
So 152565-63-4 is a valid CAS Registry Number.
