Check Digit Verification of cas no

The CAS Registry Mumber 127825-08-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,8,2 and 5 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 127825-08:
(8*1)+(7*2)+(6*7)+(5*8)+(4*2)+(3*5)+(2*0)+(1*8)=135
135 % 10 = 5
So 127825-08-5 is a valid CAS Registry Number.

MIXED CARBOXYLIC - CARBONIC ANHYDRIDE METHOD IN PHOSPHONO PEPTIDE SYNTHESIS

Kafarski, Pawel,Lejczak, Barbara

, p. 7387 - 7396 (1989)

Factors influencing the reaction yields and formation of the side products during coupling of N-carbobenzoxyamino acids with dialkyl or diphenyl aminoalkylphosphonates, by means of mixed anhydryde procedure, were evaluated.The recommended procedure, arising from these studies, involves the use of chloroform/ethyl chloroformate/triethylamine system and delicate warming of the reaction mixture during the coupling step.
