106763-31-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 106763-31-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,6,7,6 and 3 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 106763-31:
(8*1)+(7*0)+(6*6)+(5*7)+(4*6)+(3*3)+(2*3)+(1*1)=119
119 % 10 = 9
So 106763-31-9 is a valid CAS Registry Number.
