106749-13-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 106749-13-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,6,7,4 and 9 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 106749-13:
(8*1)+(7*0)+(6*6)+(5*7)+(4*4)+(3*9)+(2*1)+(1*3)=127
127 % 10 = 7
So 106749-13-7 is a valid CAS Registry Number.
