Check Digit Verification of cas no

The CAS Registry Mumber 1375488-03-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,5,4,8 and 8 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1375488-03:
(9*1)+(8*3)+(7*7)+(6*5)+(5*4)+(4*8)+(3*8)+(2*0)+(1*3)=191
191 % 10 = 1
So 1375488-03-1 is a valid CAS Registry Number.

Unexpected observations during the total synthesis of calothrixin B-sodium methoxide as a source of hydride

Bhosale, Shrikar M.,Momin, Aadil A.,Kunjir, Shrikant,Rajamohanan,Kusurkar, Radhika S.

, p. 155 - 162 (2014)

During the total synthesis of calothrixin B, various novel and unexpected results were noticed such as cleavage of C-N bond in imine using sodium cyanoborohydride, sodium methoxide as a hydride source for reduction, deformylation in the presence of bromine, and deacylation using ceric ammonium nitrate (CAN). A detailed mechanism has been proposed for the unexpected results and a few of them are generalized. Temperature dependent NMR studies have been carried out for confirmation of the structure of one of the intermediates in the synthetic sequence.
