229156-92-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 229156-92-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,9,1,5 and 6 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 229156-92:
(8*2)+(7*2)+(6*9)+(5*1)+(4*5)+(3*6)+(2*9)+(1*2)=147
147 % 10 = 7
So 229156-92-7 is a valid CAS Registry Number.
