131802-37-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131802-37-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,8,0 and 2 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 131802-37:
(8*1)+(7*3)+(6*1)+(5*8)+(4*0)+(3*2)+(2*3)+(1*7)=94
94 % 10 = 4
So 131802-37-4 is a valid CAS Registry Number.
