1190929-31-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1190929-31-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,0,9,2 and 9 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1190929-31:
(9*1)+(8*1)+(7*9)+(6*0)+(5*9)+(4*2)+(3*9)+(2*3)+(1*1)=167
167 % 10 = 7
