155374-30-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 155374-30-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,3,7 and 4 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 155374-30:
(8*1)+(7*5)+(6*5)+(5*3)+(4*7)+(3*4)+(2*3)+(1*0)=134
134 % 10 = 4
So 155374-30-4 is a valid CAS Registry Number.
