106237-77-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 106237-77-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,6,2,3 and 7 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 106237-77:
(8*1)+(7*0)+(6*6)+(5*2)+(4*3)+(3*7)+(2*7)+(1*7)=108
108 % 10 = 8
So 106237-77-8 is a valid CAS Registry Number.
