Check Digit Verification of cas no

The CAS Registry Mumber 858972-98-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,8,9,7 and 2 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 858972-98:
(8*8)+(7*5)+(6*8)+(5*9)+(4*7)+(3*2)+(2*9)+(1*8)=252
252 % 10 = 2
So 858972-98-2 is a valid CAS Registry Number.

Total synthesis of hirsutellide A

Xu, Yanjie,Chen, Ligong,Duan, Xuemin,Meng, Yi,Jiang, Liqin,Li, Meiling,Zhao, Guangle,Li, Yang

, p. 4377 - 4379 (2005)

The total synthesis of hirsutellide A 1 was described. The linear hexadepsipeptide precursor 2 was synthesized in 45% yield from N-Boc-Me-Gly by three coupling reactions with DCC, HATU and BOP-Cl, respectively. Macrocyclization was successfully performed on the fully deprotected amino acid 14 with BOP-Cl in 15% yield and with FDDP in 22% yield.
