163237-31-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 163237-31-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,3,2,3 and 7 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 163237-31:
(8*1)+(7*6)+(6*3)+(5*2)+(4*3)+(3*7)+(2*3)+(1*1)=118
118 % 10 = 8
So 163237-31-8 is a valid CAS Registry Number.
