Check Digit Verification of cas no

The CAS Registry Mumber 1619970-86-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,1,9,9,7 and 0 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1619970-86:
(9*1)+(8*6)+(7*1)+(6*9)+(5*9)+(4*7)+(3*0)+(2*8)+(1*6)=213
213 % 10 = 3
So 1619970-86-3 is a valid CAS Registry Number.

Synthesis of multi-functional alkenes via Wittig reaction with a new-type of phosphorus ylides

Tsai, Yi-Ling,Syu, Siang-En,Yang, Shu-Mei,Das, Utpal,Fan, Yu-Shiou,Lee, Chia-Jui,Lin, Wenwei

supporting information, p. 5038 - 5045 (2014/07/08)

A Bu3P-mediated mild and efficient synthesis of multi-functional alkenes has been described starting from substituted acrylate with aldehydes. In situ generated zwitterionic intermediates underwent proton-exchange to afford ylide intermediates, which were trapped by corresponding aldehydes providing the products in up to 92% yield with complete E-stereoselectivity. Further derivatization of the products was performed to furnish functional pyridazinones.
