156274-11-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 156274-11-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,2,7 and 4 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 156274-11:
(8*1)+(7*5)+(6*6)+(5*2)+(4*7)+(3*4)+(2*1)+(1*1)=132
132 % 10 = 2
So 156274-11-2 is a valid CAS Registry Number.
