1337541-80-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1337541-80-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,7,5,4 and 1 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1337541-80:
(9*1)+(8*3)+(7*3)+(6*7)+(5*5)+(4*4)+(3*1)+(2*8)+(1*0)=156
156 % 10 = 6
So 1337541-80-6 is a valid CAS Registry Number.
