Check Digit Verification of cas no
The CAS Registry Mumber 38270-72-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,8,2,7 and 0 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 38270-72:
(7*3)+(6*8)+(5*2)+(4*7)+(3*0)+(2*7)+(1*2)=123
123 % 10 = 3
So 38270-72-3 is a valid CAS Registry Number.

The present invention relates to a conjugate of the formula P-L-I, wherein P is a peptide hormone effecting the metabolism of carbohydrates in vivo, L is a hydrolysable linker molecule consisting of Lp and Lj, and I is a molecule capable of inhibiting the effect of the peptide hormone P on the metabolism of carbohydrates in vivo. Under in vivo conditions, the conjugate is the major compound. When the concentration of glucose increases in v/vo,the concentration of the peptide hormone effecting the metabolism of carbohydrates in vivo also increases.
