155338-66-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 155338-66-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,3,3 and 8 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 155338-66:
(8*1)+(7*5)+(6*5)+(5*3)+(4*3)+(3*8)+(2*6)+(1*6)=142
142 % 10 = 2
So 155338-66-2 is a valid CAS Registry Number.
