Check Digit Verification of cas no

The CAS Registry Mumber 108277-81-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,2,7 and 7 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 108277-81:
(8*1)+(7*0)+(6*8)+(5*2)+(4*7)+(3*7)+(2*8)+(1*1)=132
132 % 10 = 2
So 108277-81-2 is a valid CAS Registry Number.

Ring Expansion of Cyclic α-Ethynyl Sulfonium Ylides by -Sigmatropic Rearrangement: Formation of Thiocin, Thionin, and Thiecin Derivatives

Sashida, Haruki,Tsuchiya, Takashi

, p. 3644 - 3652 (2007/10/02)

The cyclic 1-ethoxycarbonylmethyl-2-ethynyl sulfonium salts (15Aa-d, 15Ba-d, and 15Ca-d),prepared from thiolane (12A), thiane (12B), and thiepane (12C), were treated with 1,5-diazabicycloundec-5-ene (DBU) to result in ring expansion, giving thiocin
