178244-37-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 178244-37-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,8,2,4 and 4 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 178244-37:
(8*1)+(7*7)+(6*8)+(5*2)+(4*4)+(3*4)+(2*3)+(1*7)=156
156 % 10 = 6
So 178244-37-6 is a valid CAS Registry Number.
