1206905-29-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1206905-29-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,6,9,0 and 5 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1206905-29:
(9*1)+(8*2)+(7*0)+(6*6)+(5*9)+(4*0)+(3*5)+(2*2)+(1*9)=134
134 % 10 = 4
So 1206905-29-4 is a valid CAS Registry Number.
