Check Digit Verification of cas no

The CAS Registry Mumber 1621614-80-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,1,6,1 and 4 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1621614-80:
(9*1)+(8*6)+(7*2)+(6*1)+(5*6)+(4*1)+(3*4)+(2*8)+(1*0)=139
139 % 10 = 9
So 1621614-80-9 is a valid CAS Registry Number.

An unusual Wittig reaction with sugar derivatives: Exclusive formation of a 4-deoxy analogue of α-galactosyl ceramide

Sawant, Ratnnadeep C.,Lih, Yu-Hsuan,Yang, Shih-An,Yeh, Chun-Hong,Tai, Hung-Ju,Huang, Chung-Li,Lin, Hua-Shuan,Badsara, Satpal Singh,Luo, Shun-Yuan

The Wittig reaction of the pyrano-type reducing sugars undergoes an unexpected formation of dienes through the elimination of a benzyloxy group in the presence of t-BuOK. LiHMDS is used rather than t-BuOK to prevent alcohol elimination in the same sugar derivatives. Collectively, t-BuOK has unusual functions in the Wittig reaction that correspond with other bases such as LiHMDS, NaH, and n-BuLi. This unusual function of t-BuOK showed that a unique 4-deoxy-5-hydroxyl analogue 2 of α-galactosyl ceramide was formed exclusively.
