1227734-10-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1227734-10-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,7,7,3 and 4 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1227734-10:
(9*1)+(8*2)+(7*2)+(6*7)+(5*7)+(4*3)+(3*4)+(2*1)+(1*0)=142
142 % 10 = 2
So 1227734-10-2 is a valid CAS Registry Number.
