Check Digit Verification of cas no
The CAS Registry Mumber 152033-72-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,2,0,3 and 3 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 152033-72:
(8*1)+(7*5)+(6*2)+(5*0)+(4*3)+(3*3)+(2*7)+(1*2)=92
92 % 10 = 2
So 152033-72-2 is a valid CAS Registry Number.
